The Best Anti-Ageing Ingredient: Larecea™ Extract
What is Larecea™ Extract?
The Dr.TWL Dermaceuticals Larecea™ Extract originates from the leaves of Brassica oleracea, an edible vegetable whose leaves are used as a skin wound healing agent. This vegetable has high nutritional value, with high concentrations of calcium, protein and ascorbic acid. Belonging to the family Brassicacea (cruciferae), this plant is cultivated by farmers and distributed worldwide, although most commonly found in temperate regions.
The Romans have been using the plant in the form of poultices to treat wounds, while Brazilian folk medicine relied greatly on the plant extract for medicinal purposes. Beyond traditional folk medicine, clinical studies have revealed Larecea™ Extract’s abilities to heal wounds.
How does our skin heal wounds naturally?
Healing of skin wounds is a physiological process. Our skin aims to restore the continuity of tissues, through a systemic, healing process. Tissue injuries can reach different layers of our skin and potentially alter the physiological structure of the skin.
You may be visualizing skin wounds as a minor cut or scratch on your body, but it can also refer to acne scars on your face. Such scars on the face can make us feel self-conscious and cosmetically debilitating, thus the need for skincare products to hasten the healing process.
The synthesis of extracellular matrix is an essential feature of the wound healing process. The extracellular matrix is a gel-like matrix and comprises a large component of the dermal skin layer. Containing a variety of polysaccharides, water and collagen proteins, it allows the skin to have substantial elasticity and compressibility.
In normal, healthy skin, about 80 per cent of the extracellular matrix corresponds to type I collagen, while type III collagen accounts to 10 to 20 per cent. Collagen molecules become cross-linked to surrounding collagen molecules to create additional strength and stability in collagen fibers.
In the case of tissue injury, the beginning of the repair process has type III collagen dominating the extracellular matrix, causing the matrix to be more fragile. Type III collagen forms as a support for the deposition of type I collagen, which is thicker and has higher resistance against scar tissue.
The collagen fibres are weak and thin at this point, with the strength of the extracellular matrix only reaching 3 per cent of intact tissue after the first week. Enzymes of collagen and protein continue to cleave and degrade the collagen fibers.
As type III collagen is slowly replaced by type I collagen, the extracellular matrix slowly regains its strength, organization and thickness. The typical original strength is reached by three months.
How long does it take for a wound to heal?
According to Dr Teo Wan Lin, an accredited dermatologist at TWL Specialist Skin and Laser Centre, she says, “The time required for a skin wound to heal will depend on the depth and the distance between the wound edges. Often, superficial wounds do not bleed and take approximately a week for complete recovery.
When the dermis, the thick skin layer below the epidermis, is damaged, our skin cells begin repair at the wound edges. The scar can take up to 12 to 18 months to heal completely. Wounds found on our face heal more rapidly due to the excellent dermal blood supply to the head and neck.”
What can Larecea™ Extract do?
So, perhaps all that you have understood so far is that wound-healing is a slow process, as your collagen fibers are weaker and need time to be replaced by good collagen. Now you may begin to wonder, how exactly can Larecea™ help?
There is greater tensile strength of the wounds when treated with the Larecea™ Extract, with the production of connective and epithelial tissues that help form the framework. Collagen fibers enter an earlier phase of wound healing with Larecea™, with a greater number of collagen fibers emerging from treatment with the extract as compared to without. A superior grade of maturation can also be observed in the collagen fibers.
Another factor that can affect a wound’s rate of recovery is the rate of re-epithelialisation of the skin tissue which the Larecea™ supports. Essentially, it refers to the reconstruction of an organized and intact epithelium, to help in covering the wound defect and allows the restoration of functions. A higher number of cell divisions will lead to a greater expression of growth factors. This allows the receptors to help facilitate the recovery of the epithelium, leading to the intensified repair process in our skin cells.
In essence, Larecea™ Extract is able to accelerate wound healing and repair of the extracellular matrix. As the time needed to heal a wound is reduced, Larecea™ Extract significantly cuts down any potential risks of infection and possible complications, also leaving less unsightly scars due to its strong repairing functions.
